The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Orange and egg barely smell alike, yet cooks put them together in 10,696 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Marrow bone
Simmered in water to release flavour and richness into the broth.
Eggs
Poached until set, adding soft protein body and mild richness to the soup.
Juice of 1 ripe orange
Adds acidity to the poaching water, brightening the dish.
Pieces of bread
Soak up broth, adding softness and body to each serving.

The step that matters

Cook the eggs until they float to the top. Eggs set gradually in simmering acidic water; overcooking makes the whites rubbery and the yolks chalky, so timing needs watching.

Swap the orange

How well each one fits the dish's main ingredients (egg, bread):

  1. Datesfits better
  2. Pumpkinfits better
  3. Figfits better
  4. Orangethe original

Fit is the average pairing score against egg, bread. Candidates are from the same food group and used in at least 100 recipes.
